Title: Data storage apparatus
IPC: B41B27/02
Filed: 1972-10-31
Abstract: 1369384 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1972 [1 Nov 1971] 50053/72 Headings G4H and G4A Data storage apparatus comprises a shift register operable to store a series of codes and having input and output stages interconnected to form a closed loop, the series including two sections of character-representing codes divided from one another by a separator code, each section being further subdivided by controlling codes, decoding means to detect the controlling and separator codes passed between the input and output stages, and gating means operable, in response to the decoding means, to gate character codes to a data receiving means alternately from the two sections under the control of the controlling and separator codes. The shift register is N bits wide. Its output feeds the decoding means and can be fed via a first buffer register, a normal register, an insert register and a second buffer register back to the input of the shift register, though usually the insert register is by-passed. Both the normal and the insert registers can be by-passed. A data buss connected to a printer and keyboard, and to a record reader, can be fed from the first buffer register and can feed the second buffer register. One of the two sections of the series of codes can include an operation code, defining the section as that which has to be addressed for reading or writing of codes, the other section containing a hold code. The two sections can hold respective texts entered from cards or by keying, and which have to be merged and printed out. A section button specifies whch section is to be addressed, and if this is inconsistent with the specification provided by the hold and operation codes these are automatically interchanged. Assuming then that the section with the operation code is being addressed for print-out, readout for printing starts at the operation code and continues (with movement of the operation code along the series as successive codes are output) until a switch code is encountered when the operation and hold codes are interchanged and read-out continues from the new position of the operation code (i.e. in the other section) until another switch code is encountered when the system returns to the first section in the same way, and so on. Print out can be stopped by stop codes in the sequence, when the operator can cause it to continue in the other section using the section button. A clear button can be used to clear either section.

Title: Fluid flow metering method and apparatus
IPC: G01F15/02
Filed: 1969-01-29
Abstract: 1,272,049. Flowmeters. HALLIBURTON CO. 29 Jan., 1969, No. 50072/71. Divided out of 1,267,441. Heading G4H. In a fluid flowmeter each pulse from the meter sets a bi-stable 20 (Fig. 6) to enable (1) a gate 28 to pass high frequency pulses and (2) a gate 14 to allow pulses the frequency of which represents a variable condition of the fluid, e.g. its oil content to enter a divider 22, the output from which resets bi-stable 20 to close the gate 28. In the embodiment of Fig. 3 (not shown) the high frequency pulses from oscillator 30 may be made proportional to the fluid pressure, the pulses that pass gate 28 being counted in counter 34 the count in which represents the flow compensated for the variable condition. A further counter (26) counts the total pulses from the flowmeter 16. In a modification (Fig. 6) the output of gate 28 after scaling is subtracted from the scaled output of the flowmeter the subtractor being connected to a counter 44 the count in which represents the oil content. A friction compensator 36 may be included to compensate for the bearing friction of the flowmeter 16. A further counter may give the water content by subtracting the content of counters 26 and 44. In the embodiment of Fig. 7 the time for which bi-stable 76 is set is made to vary with the temperature of the fluid. This is effected by using a second capacitance diode 60 in a closed cell 62 the frequency output f<SP>11</SP> of which thus only varies with the temperature of the fluid flowing. After the bi-stable 76 has been set by a pulse from the flowmeter AND gates 84, 88 are enabled to pass the frequency signals f<SP>11</SP>, f<SP>1</SP> from the capacitance probes to dividers 96, 100. The output of divider 96 resets the bi-stable 76 to close the AND gate 88 the output of divider 100 being fed, via a subtractor 80 where it is subtracted from pulses from the flowmeter, to a counter 82. Consequently gate 88 is enabled for a time dependent on the temperature of the fluid to count pulses the rate of which also depends on the temperature so that errors due to variations in temperature are eliminated. The two capacitance probes may receive the same supply to compensate for drift.

Abstract: 1441149 Sheathing cables by extrusion SCHLUMBERGER TECHNOLOGY CORP 29 Oct 1973 [30 Oct 1972] 50173/73 Heading B5A [Also in Division H1] In the manufacture of a well-logging cable the centre conductor 10 is formed by spiralling conductive wires 20 around a plastic monofilament, a fluorocarbon polymer for examples and then heating the wire under tension so that they partially embed in the monofilament. The resulting configuration is then passed through extruders where the external interstices between the wires 24 are filled with thermoplastic filler material and a layer of insulation 25, is applied overall. This insulation may be a fluorocarbon polymer. The completed conductor 10 is then fed into an extruding device which applies neoprene or other semi-conductive elastomer to form the matrix member 11 and from there to a closing die at which the solid insulated conductor 12 are spiralled around and embedded in the matrix 11. In a second extruding device the uncured outer sheathing material 13 is applied under pressure to cause the matrix material to extrude about the outer parts of the conductors 12 and to merge with the inner core member 10. The assembly is then cured in an oven which forms the sheathing in to a monolithic body firmly embedding the conductors with substantially no voids. Finally inner and outer armour wires 15 and 16 are applied by known means.

Abstract: 1435623 Loud-speakers J G DAHLQUIST 12 Nov 1973 [29 Nov 1972] 52435/73 Headings H4J and H4X In a multiple permanent magnet transducer assembly the bais unit is mounted in its own enclosure and one or more h.f. transducers are mounted in an acoustically transparent compartment outside the bais enclosure by means presenting minimal frontal area and allowing almost all of the transducer to be surrounded by free space. This arrangement prevents the formation of secondary sound sources at discontinuities, particularly the edges, of baffles carrying h.f. transducers which would otherwise produce time delay and intermodulation distortion. The h.f. units are staggered, Fig. 3, according to response time, the fastest being rearmost, so that sounds from each unit reach the on-axis listener at the same instant. The distances may be determined empircally using a square wave source covering frequencies of two adjacent units and determining by microphone and oscilloscope when the reproduced square wave has the best shape. The rear face of the compartment may be acoustically semitransparent to reduce rearward radiation. In a modification (Figs. 5, 6, not shown) a single support for all h.f. units is stepped to the appropriate dimensions.
